Just found these two sets of instructions from Rodney. You may have to do it a little bit differently than the instructions from DQ due to the way the GEM is wired.
Updated (?) from 2019:
To prepare to change the algorithm on a Delta Q on most GEM cars you will need 2 pieces of insulated electrical wire about 6 feet long connected to a momentary pushbutton switch.
The reason for this is that you will be flat on your back where you can see the indicator lights on the DQ while changing the setting.
Let’s get started.
Shut the main switch off.
Disconnect the red wire coming from the charger at the B+ (battery plus) post.
Connect one of your pushbutton wires to the post and pos…

DELTA’Q PROGRAMMING INSTRUCTIONS FOR FACTORY INSTALLED D’Q CHARGERS
The charger comes pre-loaded with charge algorithms as detailed in Table 1. Each time AC power is applied with the battery pack NOT connected, the charger enters and algorithm display mode for about 11 seconds. During this time, the current algorithm # is indicated by the number of blinks of the ‘’ LED and Remote LED. A single-digit Algorithm # is indicated by the number of blinks followed by a pause. A 2-digit Algorithm # is i…
I just only skimmed them, but It looks like Rodney is recommending a slightly different method and hook up.
